Biology

Rare breeding migrant. Inhabits the dry steppes and semi-deserts with the patches of saline soils and sparse vegetation, usually near water (not far than 1-2 km). In spring arrives by small flocks of one-two dozen birds from the mid-March, mostly in April – early May. Breeds in separate pairs, or in loose colonies of 10-15 pairs at distance 50-150 m one from another. Nest is shallow hole which is usually lined with the dry grass, sheep droppings or pebbles, but sometimes without anything. Clutches of 2-5 (usually 4) eggs is produced from end of April to early June. Repeated nesting after loss of first clutch is not rare. Both parents (but mostly female) incubate for 17-21 days and care for juveniles which hatch from the end of May to mid-June and begin to fly in end June – July. Broods join in flocks numbering up to one hundred and more birds and begin to disperse. Autumn migration begins from early August. The latest records apply to September 20th (Naurzum), October 10th (near Kazalinsk), October 15th (close to Tashkent ).
